VFUEL BURNER.

`App1icaton1ed March 6, 1,925. Serial Ned3-,577.

To @ZZ @fifi om t may concern.:

Be it known that l. lVILLrAM. D. S'rAoEr, a citizen of Great Britain,-residing at Vancouver. in the county of Clarke and State of lfasliington7 have invented certain new and useful improvements in Fuel Burners, of which the following is a specification.

This intention relates to fuel burners and pertains particularly tothe class of hydrocarbon burners.

The primary object of this invention is the provision, in a manner as hereinafter set forth, of a hydrocarbon burner designed to use steam in connection with the hydrocarbon, and further designed to atomiyethe fuel and the steam to form a perfectly combustible fuel.

[another object of the invention is they provision, in a manner as hereinafter set forth, of a hydrocarbon oil burner having a plurality of atomizers in the body thereof whereby a perfectly mixed spray of the oil and steam 'will be discharged from the burner portsfor proper combustion.

rlhe invention contemplates the provision of a circular cast body having a pair of superposed chambers in the central -portion thereof, the upper chamber being of materially greaterdiameter than the lower chamber. Each chamber has an inlet port leading thereto. Extending downwardly lfrom the floor ofthe chamber of greater diameter about the wall thereof is a series of passages which extend downwardly to a point approximately in alignment with the Hoor of the lower chamber whereupon the passages turn at right angles and extend outwardly radially of thebody opening upon the side thereof'. Extending radially from the ylower chamber is a series of relatively narrow passages each one of which opens into the lower end of one of said vertical passages. These narrow passages atomize steam forced therethrough from the smaller chamber to thoroughly mix with oil drawn from the upper chamber through the vertical passages, the mixture burning at the outer ends lof the passages which open upon the outside of the body. f

. further and iinal object of the invention is the provision, in a manner as hereinafter set forth, of a hydrocarbon oil burner of simple construction, highly etlicient, and inexpensive to cast and set up.

The invention will be best understood from a consideration of the 'following de-Vv spect-ively.

tailed description taken in connection with Fi'g. l is a vertical section'through the device embody-ing this invention and through 'a portionl of an attached fuel oil and steam inlet pipes.. i

Fig.i 2 is thehorizontal-section'talren'upon the line 2-2 of Fig. 1.

Fig. 3 is a vertical section taken upon the f line 3 3 of Fig. 1

"Fig l is a horizontal section taken upon the linea-#1ll of Fig. l.

Referring now to the drawing-s 1n detail` whereinv likenumerals of reference indicate corresponding parts throughout the sev/'eral views, there is indicated generally by the numeral 1k the body of the device embodying thisy invention. This body may be formed of cast metal and'thoiigh the drawing shows the same as of'circular contour7 it is to be understood that applicant vdoes not limit himself to this shape for the body may bc cast 'in any desired shape without altering the effectiveness of the burner.

Upon the top ofthe bodykl there is cast the substantially semi-circular boss Q, which extendsfrom oneside of the casting to the central portion thereof as shown in Fig. l, and oilinlet passage 3 is formed through the longitudinal center of this boss and turns downwardly as at right angles l where it opens into the top of the upper one of a pair of superposed c hambersv 5 and 6 re- The chamber 5 is of materially greater diameter than the chamber 6 as clearly shown in Fig. l, and this chamber constitutes what may be termed an oil manifold. steam inlet passage 7 which is here shown beneath and parallel with the passage' 3 and this passage 7 is materially constricted as at 8 as the chamber 6 is considerably less in height than the diameter of the inlet passage 7.

The outer portion of each of the passages '3 and 7 is interiorly threaded as at 9 to receive the threaded ends of the eiland steam The body l has formed therein the with the floor of the chamber G. These ver-Y tical passages 1'2 are vshown in Fig. 2 as extending throughout onehalf only of the circumference of the chamber 5, but it is to be understood that a larger series may be employed than that here shown.

Extenoing radially from the lower chamber G and opening the-reinto through the wall thereof is a series of atomizer tubes or passages 13, each one of these passages opening into the lower end of one of the vert-ical passages 12. Y

Extending radially through the body 1 from the lower end ofv and at right angles to each of the vert-icall tubes 12 is a burner tube le, the mouth 15 of; each of which opens on the outside of the body 1.

As before stated, the passages 12, 13 and 14 are shown as extending throughout onehalf only of the circumference of the body 1, but it is of course apparent that the same may be increased or decreasedin number to give a blaze of greater or smaller spread. This can be accomplished eqaallyas well by a` burner of a contour different from that shown in the drawings and applicant does not limit himself to a burner of the contour shown.

l? rom the foregoing description itwill be seen that when the burner is in use, steam entering the chamber 6 under pressure and forcing its way through the narrow passages or atomi/ser tubes 13 into the outlet burner passages lei, will create a suction or vacuum in the chamber 5 and 'tubes 12 thereby drawing'- fuel oil thereinto through the pipe 3 where the same will be atomized with the steam in its passage through the tube lil and a` complete combustion of the fuel mixture will be had at the mouth 15 of the burner passages. Suit-able valves may be placed in the pipe lines 10 and 11 and when the oil supply has been once properly regulated to produce the proper mixture kwith the steam,

- the steam pipe valve need be the only one toV levarsi be regulated for when the flow of steam through the atomizer tubes ceases upon the closing of the steam pipe line 11, the suction inthe chamber 5 will be stopped and the oil will cease to flow.

From the foregoing description it will bev tering through the top thereof, means to provide an inlet for the lower cham-ber en- Y tering through the side thereof, said lower chamber being materially smaller than said upper chamber and having the inl-et thereto censtricted, 'said upper chamber having a. fuel discharge port leadingv therefrom to the exterior of said body andlsaid lower chamber having a steam discharge port of materially less diameter than said fuel discharge port and leading'thercfroin and merging with said fuel port.

Q. A hydrocarbon burner of the character described, comprising a body-having formed therein a pair of superposed chambers, the upperof said chambers being of greater diameter than the lower one and having a series of downwardly extending passages opening through the lioor adjacent the wall thereof, said lower chamber having a radially extending series of relatively narrow passages leading therefrom, each opening into `the lower end of a downwardly extending` passage, and said body having a radially extending series of passages of larger diameter than said narrowrpassage, leading from the lower end of said vertical passages to the outside of said body. and each in alignment with one of said narrow Vpassages..
